“…[1][2][3][4][5] Previous studies on airway morphology of patients with Class III malocclusion have been focused on the change of airway dimension after treatment with protraction headgear, 6 mandibular setback, 7,8,9 or bimaxillary surgery. 10 Ritcher et al 11 reported two cases of obstructive sleep apnea syndrome found in asymmetrical patients, indicating that upper airway obstruction could exist in patients with mandibular asymmetry.…”

Objective: To compare the three-dimensional (3D) morphology of the upper airway in skeletal Class III patients with and without mandibular asymmetry and to investigate the possible underlying correlations between the morphology of the upper airway and mandibular deviation. Materials and Methods: Cone-beam computed tomography images of 54 subjects with skeletal Class III malocclusion (ANB angle 0.48, Wits À5.58) were taken and 3D upper airway models were reconstructed using Dolphin 3D software. According to the distance (d) from symphysis menti to the sagittal plane, all subjects were divided into a symmetry group (d 2 mm) and an asymmetry group (d ! 4 mm). Based on the severity of mandibular deviation, the asymmetry group was divided into subgroup I (4 mm d ,10 mm) and subgroup II (d ! 10 mm). Cross-sectional linear distances, areas, and volumetric variables of the upper airway were measured in the 3D airway model. Results: Width of the inferior limit of the glossopharynx (P3W), cross-sectional area of the anterior limit of the nasal airway (P5S), and height of the glossopharynx (GPH) in the asymmetry group were significantly larger than in the symmetry group. As for subjects with severe mandibular deviation in subgroup II (d ! 10 mm), volume of the glossopharynx (GPV), total volume of the pharynx (TPV), length of the inferior limit of the velopharynx (P2L), and ratio of length to width of the inferior limit of the velopharynx (P2L/P2W) showed significantly negative correlations with mandibular deviation (r . 0.7, P , .05). Conclusions: In Class III subjects with severe mandibular asymmetry, the pharyngeal airway showed a tendency toward constriction and presented a more elliptical shape as mandibular deviation became more severe (P , .01).

“…The current view is that adenotonsillar hypertrophy, which constricts the airway, is the major cause of sleep-disordered breathing in otherwise healthy children. 6,7 Sleep-disordered breathing may affect pulmonary ventilation, oxygenation, sleep quality, sweating, and nocturnal enuresis. 8,9 In children, behavioral problems and impaired cognitive performance may also be encountered.…”

Objective: To evaluate how therapy with a fixed functional appliance affects airway dimensions, dentoalveolar changes, and tongue and hyoid positions. Materials and Methods: A retrospective study was carried out on 46 pre-and posttreatment lateral cephalometric radiographs of 23 post-peak Class II patients (12 girls, 11 boys) treated with a Forsus Fatigue Resistant Device (FRD) appliance. The radiographies were taken at the start and at the end of Forsus FRD appliance therapy when a Class I or overcorrected Class I canine and molar relationship was achieved. The process took an average of 5 months 13 days 6 1 month 4 days. Skeletal and dental parameters were measured using Dolphin software, and the sagittal airway area was measured by AutoCAD software. Results: Analyses of the pre-and posttreatment means revealed that there was no statistically significant skeletal correction of the sagittal malocclusion; increase of lower incisor inclination, decrease of upper incisor inclination, decrease of interincisal angle, and rotation of occlusal plane all contributed to the reduction of overjet. The tongue area and intermaxillary space area increased in response to these dentoalveolar changes; however, there was no statistically significant change in the hyoid position or the oropharyngeal area between the two time points. Conclusions: The dentoalveolar changes produced by Forsus FRD appliance did not cause any significant posterior airway changes in young adult patients. (Angle Orthod. 2014;84:260-264.)

“…En contraste Chiang y colaboradores (26) y Bergamo y colaboradores (27) no encontraron asociación estadísticamente significativa entre la disminución de la longitud de la base de cráneo anterior con respecto a la presencia de AOS. Un desarrollo deficiente del complejo craneomaxilar (S-N) causa la disminución en la dimensione de las vías aéreas respiratorias superiores en pacientes con crecimiento hiperdivergente causando AOS (28).…”

“…En contraposición, Kawashima y colaboradores (31) demostraron un aumento en el ángulo del plano mandibular en el grupo de niños con AOS con respecto al grupo control, en una población de niños asiáticos y sugieren que en pacientes en crecimiento la obstrucción de la vía aérea superior es causada por un mayor desarrollo facial vertical. Parece que el patrón esquelético vertical predispone a una obstrucción de la hipofaringe dando como resultado una disminución del tamaño y una posición más posterior de la mandíbula lo que podría predisponer la presencia de AOS (28).…”
